I am building a S&G kayak and I am finding that as I build up layers of
epoxy the finish tends to 'orange peel' and requires a lot of sanding to get
it smooth. The first coats of epoxy went on flat.

Any help would be appreciated.

Thanks

John

Had the same problem. Did you rinse off the amine blush between coats?

I didn't rinse off the amine blush in the beginning because I was under the
impression that if you recoated with-in a day or two it was not necessary.
Also, the epoxy I used is very low blush and I didn't notice any. I since
have attempted to wash the surface with warm water but it didn't make any
difference.

Thanks

Mmmm..... interesting. I have never figured out why this was happening.

That's what happens when you use a brush intended for Polyester only ;-P

Hi,

Could be that silicone spray has been used nearby or contaminated
something, or it may even be anti-clog additives from sandpaper.

cheers,
Pete.

I neved used silicone spray. So I think it is the anti-clog additive. I did
clean though, with xylene-based thinner, but probably not good enough or the
used rag was already too dirty.

It looks exactly like that!

Wash it thoroughly with hot soapy (detergent) water to remove contaminants
and rinse very well, then sand it down and wash with warm ammonia water,
then try coating again.

If the finish looks like that, it's due to a contaminant. Either the brush
as Stephen pointed out, or something on the wood. I've seen silicon do that
from an accidental overspray of silicon lube ...the stuff should be illegal
in boat shops.
